Drying apparatus for grain and the like

ABSTRACT

A drying device for bulk grain or other substances. This device consists primarily of a hollow box-like structure having spaced away from the walls on the interior, a perforated box-like structure through which hot air is placed under pressure so as to dry the grain carried within the space defined by the walls of both of the box structures.

UNITED STATES PATENTS 3,057,080 10/1962 Haddix 34/l7 4 1 Claim, 2 Drawing Figures DRYING APPARATUS FOR GRAIN AND THE LIKE This invention relates to drying devices, and more particularly to a drying apparatus for grain and the like.

It is a principal object of the present invention to provide a device which will include a hollow square box member carried within a hollow square outer box member, the inner box serving to receive hot air under pressure that will travel outward through the perforated side walls so as to pass through the grain in order to dry it.

Another object of this invention is to provide a drying apparatus which will have an upper inlet opening for receiving the grain, the grain falling by gravity means into the space defined between the walls of the outer box member and the walls of the inner box member.

Another object of this invention is to provide a drying apparatus of the type described which will have a discharge nozzle at the lower extremity of the outer box thus enabling the grain after drying, to be discharged by means of gravity.

A further object of the new invention is to provide an apparatus of the type described which will have inlet pipe means at one of the corners of the perforated inner box, thus enabling hot air to be introduced into the interior of the inner box of the apparatus.

A still further object of this invention is to provide an apparatus of the type described which will have support frame means for rendering the apparatus stationary and the inner box will have rod brace means secured to the interior of the outer box to thus support the inner box within the outer box.

Other objects of the invention are to provide a drying apparatus for grain and the like which is simple in construction, easy to use, inexpensive to manufacture, rugged, and efficient in operation.

These and other objects will be readily evident upon a study of the following specification and the accompanying drawing wherein:

FIG. 1 is a vertical view of the present invention shown partly broken away; and

FIG. 2 is a cross sectional view taken along the line 2-2 of F IG. 1.

According to this invention, a drying apparatus is shown to consist of a support frame 11 which renders the square configurated and hollow box 12 stationary. Box 12 consists ofa plurality of side walls 12 which are fixedly secured together in a suitable manner (not shown).

Apparatus 10 also includes a hollow and square configurated inner box 13 which is fixedly secured to rods 14, the opposite ends of rods 14 being fixedly secured to the interior of the outer box 12. The side walls 15 of the inner box 13 are perforated so as to enable air (hot air) to pass outwards. The inlet opening 16 at the upper extremity of box 12 provides a means for grain 17 or the like to be introduced into apparatus 10.

The grain l7 flows into the space 18 defined by the side walls 12' of box 12 and the side walls 15 of the inner box 13.

A discharge nozzle 19 at the lower extremity of the outer box 12, enables the grain 17 after it is dried, to be discharged by gravity means from apparatus 10. The hollow main box 12 is supported on the support frame 11 so that one of the corners of the main box 12 extends downwards of the center of the support frame to form an inverted pyramid for converging the grain 17 toward the discharge nozzle 19.

It will be noted that a hot air inlet pipe 20 extends from one corner of the inner box 13 and also extends through the outer box 12 and thus provides a means for introducing hot air under pressure into the inner box 13.

In use, the grain 17 after being introduced into the space 18 is dried by the hot air passing through the perforated side wall 15 of the inner box 13.

it shall further be noted that the inherent structure of apparatus 10 serves to eliminate the former need for levelling augers at the top portion and also eliminates the former necessity for unloading augers at the bottom portion of the apparatus 10.

I claim:

1. A drying apparatus for bulk grain and the like, comprising a square and hollow mainbox, a support frame for said box for rendering it stationary and elevating it, a perforated smaller inner box within said main box for hot air to be introduced into the grain to be dried, an inlet opening to said main box for the in troduction of grain and the like, a discharge nozzle from said main box for said grain after it is dried, said main box being supported on said support frame so that one of the corners of said main box extends downwards of the center of said support frame thus enabling the dried grain to be discharged by gravity means from the discharging nozzle, said downward corner forming an inverted pyramid for converging said grain toward said discharge nozzle, the opposite corner of said main box including an extending inlet member for receiving grain, a space between boxes for said grain being equal between each of the related and parallel side walls of said boxes, said inner and perforated box being secured to a pipe extending through and out of said main box, hot air being carried through said inner box, said hot air passing outwards through the perforated side walls of said inner box and into said grain, thus drying said grain, said hot air inlet pipe extending from said inner and perforated box outwards through said main box and being connected to a hot air source.
